Nelson was found guilty of killing her son by crossing the road in the “wrong” place. But what about the highway designers, traffic engineers, transit planners and land-use regulators who placed a bus stop across from apartments but made no provision whatsoever for a safe crossing? Those who ignored the fact that pedestrians always take the shortest possible route but somehow expected them to walk six-tenths of a mile out of their way to cross the street? Those who designed this road — which they allowed to be flanked by apartments and houses — for speeds of 50 mph and more? And those who designed the entire landscape to be hostile to people trying to get to work or carrying groceries despite having no access to a car? Are they not culpable?

This phenomenon is not unique to metro Atlanta. Transportation for America researched 10 years’ worth of pedestrian fatalities nationwide and found this pattern again and again. The bodies line up like soldiers along certain corridors — the first clue that the roadway is not designed for the safety of the pedestrians who are obviously using the road.

This is a major issue in inner-ring suburbs across the country, places originally built as auto-only suburbia that now are home to many lower-income families who don’t have access to cars. Neither the public transportation system nor the highway designs work for those who live, work and walk in these areas. People are being punished and killed simply for being pedestrians. Our research shows that thousands of lives could be saved — and millions more lives improved — by retrofitting these dangerous roads, as many communities are trying to do.

Millions of Americans are walking, bicycling and catching the bus along roads that are not properly designed to accommodate them. Twenty-five percent of walking trips are on roads with no sidewalk or shoulder; bike lanes are available for only 5% of bike trips. This makes our streets more dangerous and encourages more people to drive to meet their needs.

Our transportation system should provide for the one-third of Americans who do not drive, including the elderly, the poor, and the young. Without walking, biking, or transit they have no opportunities for mobility.

Roads designed only for cars hamper development of compact, walkable communities. These streets deter people who might choose to drive less and avoid the high cost of gas if safe options were available.
